But I wouldn't suggest it to a newbie, who thinks that a resistor divider is an appropriate way to make a stable and stiff 3.0V supply!
"I can use a high value resistor to reduce the current consumption." makes me certain that I would not suggest much either.

However, you did not, in your post say "newbies should not intermix", but "do not intermix". Posts are supposedly read by people of different levels and, if you know what you are doing, I see no problem with intermixing.
